Description

A kind of without abrasion jar mill sand cylinder stopping means

Technical field

This utility model relates to powder body milling apparatus field, particularly relates to a kind of without abrasion jar mill sand cylinder limit Position device.

Background technology

At present sand cylinder (tank) stopping means the most on the market be rotated by actuator drives driving shaft, Frictional force drive sand cylinder rotate together with driven pulley, in order to prevent sand cylinder landing from axle two stopper, Increase a rib (being fixed together with axle) at driving shaft or driven shaft two stopper, thus play spacing work With.This stopping means is owing to having relative motion bottom rib and sand cylinder, the most unavoidably There is sliding friction, both abrasions can be caused, affect its life-span, it addition, after rib wears away, grind Mill tube can landing.

Utility model content

For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of without abrasion jar mill grinding Cylinder stopping means, in order to solve the problems referred to above.

For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that

A kind of without abrasion jar mill sand cylinder stopping means, including rotating rib and axle, described rotation keeps off Being provided with bearing in limit, one end of described axle is provided with the shaft shoulder, and described bearing wears the most also It is located close to described shaft shoulder side, outside described bearing, is provided with back-up ring one.

Further, described rotation rib is provided with back-up ring two with the installation place of described bearing.

Further, described axle is driving shaft.

Further, described axle is driven shaft.

The beneficial effects of the utility model: this utility model by increasing after bearing, rotate rib relative to Axle can rotate, with rotation rib without relative motion bottom grinding pot such that it is able to effective Reduce or without abrasion；Back-up ring and the shaft shoulder can be limited in rotating rib on axle, can play sand cylinder To position-limiting action.This utility model under conditions of realizing meeting existing function, utilize bearing friction power Little feature, by bottom grinding pot with the rotation rib that is mounted on an axle without relative motion, thus reach Reduce or without abrasion, increase grinding pot and the effect rotating rib service life.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained, broadly falls into the scope of this utility model protection.

As shown in Figure 1, 2, grinding canister stopping means the most on the market is to be driven by actuating device 4 Dynamic driving shaft 1 rotates, frictional force drives grinding pot 8 to rotate together with driven shaft 2, in order to prevent grinding Grinding jar 8 landing from driving shaft 1 or 2 liang of stoppers of driven shaft, at driving shaft 1 or driven shaft 2 liang gear Head increases a fixing rib 9 (being fixed together with driving shaft 1 or driven shaft 2), thus plays spacing Effect.This stopping means owing to having relative motion bottom fixing rib 9 and grinding pot 8, both it Between unavoidably have sliding friction, both abrasions can be caused, affect its life-span, it addition, fixing gear After limit 9 wears away, grinding pot can landing.

As shown in Figure 3,4, spacing according to the nothing abrasion jar mill sand cylinder described in this utility model embodiment Device, including rotating rib 7 and axle, described axle is driving shaft 1, and described axle is driven shaft 2, described Being provided with bearing 3 in rotating rib 7, one end of described axle is provided with the shaft shoulder, and described bearing 3 wears On the shaft and be located close to described shaft shoulder side, outside described bearing 3, be provided with back-up ring 1.

Described rotation rib 7 is provided with back-up ring 26 with the installation place of described bearing 3.

Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode Technique scheme of the present utility model is described in detail.

This utility model is when specific works: actuating device 4 drives driving shaft 1 to rotate, grinding pot 8 Rotate under the driving of driving shaft 1, when its base contacts with rotation rib 7, due to rotation Turn and inside rib 7, be mounted with bearing 3, it is possible to rotate (relative to driving shaft 1) so that grinds Grinding jar 8 and the frictional force rotating rib 7 greatly reduce (or being zero), the shaft shoulder (platform inside axle Rank) can stop that rotation rib 7 moves axially, the back-up ring 1 of outer end is prevented from rotating rib 7 Move axially, rotate rib and be axially just completely restricted on axle, it is possible to play and prevent grinding pot 8 The effect of landing.

This utility model under conditions of realizing meeting existing function, utilize the feature that bearing friction power is little, By bottom grinding pot with axle rotate rib without relative motion thus reach reduce or without abrasion, increase grind Grinding jar and the effect rotating rib service life.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
